Please understand the PDF conversions can be messy. It has nothing to do with the Sony and everything to do with PDF being a poor format to convert FROM.
Please read the PDF section http://calibre-ebook.com/user_manual...-specific-tips and see if this helps get a better output.

Well sometimes the books look like this. This is just a random sentence.

This what I mean by messy. Hopefully this board will help me because it

seems people really know

a lot about ereaders here. I've looked at the forums here before and people

seem to know what

they are talking about. I really appreciate all the help I am getting. Thanks.

It usually looks like that sometimes worse depending on the book. With the ereader it is NOT double spaced but I had to do that since word wrap seemed to be in effect when I posted here.

The margins are all set at "5.0 pt."

I apologize for not being more specific in my first post.

What you are seeing is lines not un-wrapping (removing the newlines until the end of a paragraph) enough.
You can play with the "un-wrap factor"

Calibre tries to guess where. Changing the number (usually lower than default) a little affests the guess.
There is NO single, Magik setting. Try, look at the results, change and see which way it went ( or )
